图1 淹水胁迫及喷施S3307对小豆幼苗叶片H2O2含量的影响 T1 or T4: 幼苗期正常土壤水分, 喷施蒸馏水, 即对照; T2 or T5: 幼苗期土壤淹水胁迫, 喷施蒸馏水; T3 or T6: 幼苗期土壤淹水胁迫, 喷施S3307。其中T1~T3对应龙小豆4号, T4~T6对应天津红。同天内标以不同字母的值在P = 0.05水平上差异显著。

Fig. 1 Effects of waterlogging stress and spraying S3307 on H2O2 content in leaf of seedlings of adzuki bean T1 or T4: normal soil moisture at seedling stage, and sprayed with distilled water, that is control; T2 or T5: exposed to waterlogging stress after spraying water at seedling stager; T3 or T6: exposed to waterlogging stress after spraying S3307 at seedling stage. Among them, T1-T3 corresponds to Longxiaodou 4, T4-T6 corresponds to Tianjinhong. Values of H2O2 content within the same day with different letters are significantly different at the 0.05 probability level.
